TOPIC: Integration of shop to website

The instructions for integrating shop products to a website using iframe are clear. However, I cant find the described link for 'Integrate features' under shop. Has the link been removed and if so what's the way of integration?

I'm referring to this line: "Just go to Shop -> Integrate features in website and follow the steps. " in the page www.flickrocket.com/en/the-best-way-to-integrate-the-shop

The Shop-> Integration function has been removed a long time ago. Usually the best way is to use a sub domain directly or buy button (under Marketing/External channels/Buy Button). However, you can also integrate the sub domain via iframe, although Flickrocket does not generate the code line for you.
